Mike O’Brien says, “”Perfect” is subjective, but new data shows the optimal number of words in a subject header and what kind of language to use in a promotion, among other traits that make the ideal email.

Because so many things go into marketing emails – when to send them, how often to send them, what to write, what to highlight – how do you make one perfect?

Though it’s a subjective question, Retention Science, a retention marketing company from Los Angeles, did research in order to quantify email traits, such as exactly how many words a subject line should be (six to 10) and which month sees the most conversions (surprisingly not December).

Retention Science analyzed more than 1 billion emails over a period of two years. The subjects ran the gamut, from brick-and-mortar businesses to companies like Dollar Shave Club, which is known for being techie and innovative. In addition, the marketers represented a wide cross-section of business sizes and verticals“.
